Sorry I didn't see this thread earlier, but I put out an android app titled Fantasy Guru early last week that leverages the Fantasy Sports API. Right now I'm using the baseball and football API, and I'm looking forward to integrating the basketball and hockey. As an avid fantasy sports fan I was really glad to see Yahoo put out this API.

Hey Shane K or Sean Montgomery, I do have a couple of questions for you. If you don't mind, could you shoot me an email to development at androidfantasysports.com?

It's Open Source, and should work for others although I only tested it for myself. The interface and API have large question marks, so don't get too excited. It requires the OAuth PECL extension, along with PDO. Patches and ideas are welcome :)

Forgot to mention. My next stage (aside from cleaning up and documenting the code base) is to create a service where people can archive their boards through my site, without having to install/run the code themselves. Of course, this service will require refactoring and a much prettier interface.

In addition to the existing functionality, we have a number of upcoming enhancements that should be ready prior to the kick-off of the NFL regular season, including additional user options for buzz filtering, significant improvements to our message board indexing capabilities, and a number of new content sources. Check it out and let us know if you have any suggestions for making this a more valuable service in assisting with your drive to fantasy sports glory.

Hey guys, just wanted to mention a new app within a site that I created based on the yahoo API called Fantasy League Breakdowns.

It works like this, each day my site analyzes the players on each team in your fantasy league. We look at dozens of factors for each player and come up with a collective team rating. We store these values to rank each team in your league and so we can chart how your team progresses throughout the season.

It puts context to questions such as: Is my team consistently good throughout the season? Is my overall team better than my record suggests? Is my team fortunate to have a winning record? Which players are my weakest?

As an example, this Yahoo Public 739089 (http://www.fantasysp.com/fleague/159) was synced a few days ago. It shows where each team is ranked and their highest/lowest ratings.

it seems like a fair amount of apps have been developed in the past couple of months...

any chance Yahoo Fantasy Sports will create an app gallery in 2010 ?

I believe that most developers are like me and don't have any budget to promote their apps online (because of the non-commercial use terms)it would be great if Yahoo could give us a little bit of help to find users.I'm sure this would encourage more developers to develop great apps...

I'm putting together a series of posts for the YDN blog, and I'm looking for deep-dives (how you built your app w/technical details and code snippets) and another that would list some of the best apps that have been built with a particular API. If you are interested in being a part of either of these posts, send me an email at rtippins at yahoo-inc.com.

Very early first revision of Fantasy on Fanvibe.com has been implemented.

Fanvibe existed before as a social centric way for following sports. Naturally following fantasy matchups work the same way, so the implementation has been done.

Next steps include calculating player scores in real-time with our own stats provider, since I don't think we can hit the yahoo fantasy api as quickly. We have a live stats provider already, and would hopefully be able to map the in-progress box scores with all fantasy league statistics.

@Riley: Dude, I'm sad that I'm seeing this after the NFL season is already over -- the concept looks awesome. I'll have to try it out for baseball.

@koden:Beautiful implementation, man -- one of my coworkers had already been talking about your site weeks earlier and it was awesome to see him pull up the "games" from our Fantasy League just a couple weeks later.

Hey guys, We just launched our first app using the yahoo fantasy api that evaluates fantasy owners and ranks them according to skill. If you would like to check out our beta version its at ownerrater.mlfbaseball.com
